A screenshot of an RStudio window. On the left-hand side is a new pain called Posit Assistant. The Posit Assistant had recently run code making a lat-lon plot of Washington state, colored by whether the point had been marked as forested or not.

Today we're releasing AI for RStudio. It's really, really good—I'd encourage you to point it at the messiest data sources you have and see what it can do.

It's more that on.exit() is documented to only execute code when the currently-evaluating function context finishes; there is no such context at the top-level of an R script.

You're probably already familiar, but rtings.com is my go-to for tech hardware reviews.

on.exit() is a silent no-op at the top level in scripts and this makes me sad #rstats

it should have been %nin% 😤

something all #rstats users can agree is a good thing

it's important to share relevant instructions in your build scripts

dplyr 1.2.0 dplyr 1.2.0 fills in some important gaps in dplyr's API: we've added a new complement to `filter()` focused on dropping rows, and we've expanded the `case_when()` family with three new recoding and re...

dplyr 1.2.0 is out now and we are SO excited!

- `filter_out()` for dropping rows

- `recode_values()`, `replace_values()`, and `replace_when()` that join `case_when()` as a complete family of recoding/replacing tools

These are huge quality of life wins for #rstats!

For dplyr releases, we send a PR any time we break an #rstats package. This release advances a lot of deprecated functions, triggering issues in many old packages!

Even if you don't use it as a code generator, the tools are shockingly good at identifying real, semantic errors in the code you author.

100%. I really think Claude and Opus 4.5 have changed the game. Pretty soon, writing code without an AI assistant is going to be akin to writing Java with Notepad. If it's not already!

it was worth a shot

oh no

Are these repositories public? It does at least have, "Standard GitHub-hosted or self-hosted runner usage on public repositories will remain free."

Pricing changes for GitHub Actions GitHub Actions pricing update: Discover lower runner rates (up to 39% off) following a major re-architecture for faster, more reliable CI/CD.

Argh! @github.com announces it will start charging even for *self-hosted* runners 😥. resources.github.com/actions/2026...

I have long relied on my self-hosted runners in my teaching to run automated 'reproducibility' checks. (The edu allocation is way too small for my large classes).

tidymodels & xgboost The tidymodels ecosystem is prepared for big xgboost CRAN release.

We are excited to see that xgboost recently had a big CRAN release! We have worked hard on the tidymodels team to make sure you all have a smooth transition.

Please yet us know if you are experiencing any issues with the releases

I'm reminded of how handy the usethis::browse_*() functions are and thought I'd remind people they exist. Choose from a menu of links or go straight to CRAN or GitHub. #rstats

Quarto friends! I need your help:

We are implementing a new QMD parser in Quarto. It will be super nice. But it's a big change, and we want to minimize the impact.

1. Can you share a link to your Quarto project at github.com/quarto-dev/q...
2. repost this and let your Quarto friends know too?

Boards of Canada "Olson" on a 1959 PDP-1 Computer YouTube video by Joe Lynch

What I'm listening to today: "Olson"

Boards of Canada arranged to play on a DEC PDP-1 from 1959. The PDP-1 doesn't have sound, but it does have front-panel light bulbs for debugging, so they rewired the light bulb lines into speakers to create 4 square wave channels
